Ext5.1日期控件仅显示年月

1、注册xtype类型

2、保存文件为xxxx.js

3、使用 xtype : monthfield

   return this.buildToolbar({
                items: [
                    { xtype: 'monthfield', cId: 'dfBeginDate', labelWidth: 40, width: 150, format: 'Y-m', fieldLabel: '日期' },
                    { xtype: 'monthfield', cId: 'dfEndDate', labelWidth: 20, width: 125, format: 'Y-m', fieldLabel: '至' },
                    { cId: 'btnSearch', text: "查询", operationName: 'Search' }
                ]
            });

4、效果
